Memory calculations
Section 6 of the manual: memory calculations. Memories work in normal mode, and the memory letters are the teal labels above the keys.
Chain calculations
Section 7: chain calculations. If you start the next calculation with an operation key, the previous answer is used automatically.
Fraction calculations
Section 8: fractions. The a b over c key types fractions and switches an answer between fraction and decimal, and 2nd F d over c shows an improper fraction. On the display, a fraction is written with small corner marks: 4, corner, 5, corner, 6 means four and five sixths.
